WILLIAM E. WINE, OF F a DOOR CONSTRUCTION.

To all whom it may] concern: Beit known that WILLIAM E. WINE, a citizen of the United States, residin at T0- ledo, in the county of Lucas and tate of Ohio, has invented certain new and useful Improvements in Door Constructions, of which the following is a specification.

My invention relates to a new and useful improvement in door constructions and has -1 for an object to provide a door that will be exceptionally strong, relatively light and exceedingly simple in construction.

Another object of my invention is to provide a door construction that although relatively light-in weight, will be far stronger than a wooden one of the same size, or a wooden one that is reinforced with iron bands as is often the practice to-day.

My door is especially adapted for use on freight cars where an exceedingly strong door is' necessary, although it can advantageousl be used on any other structure, calling or a strong door.

Wooden doors at the present time are expensive to construct, relatively heavy and will not withstand for any great length of time the heavy service that they encounter when used on freight cars, as besides the normal heavy uses they are often damaged by operators forcing them open with bars or other members if for any reason they become momentarily stuck.

Metal doors as heretofore constructed, on the other hand, are formed from large heavy metal sheets which in turn make a heavy door and necessitates heavy and expensive machinery to bend or cut them to shape.

Another object therefore of my invention is to overcome the above enumerated objections and form a door that is novel in construction, quickly and readily assembled and relatively light 1n weight.

In the drawings, showing a preferred form of my invention,

Fig. 1 is a front View door construction,

Fig. 2 is an edge view thereof,

Fig. 3 is a sectional view taken on line 3-3 of Fig. 1, and looking in the direction of the arrows,

Fig. 4 is a'fragmentary perspective of one of the channel members used in the door construction,

Fig. 5 is a gusset or reinforcing member of my improved Specification of Letters ratent. Patented Mum. 211, 11922. Application filed May'Bl, 1920, Serial No. 383,087.

as shown in the blank and before being bent to its final shape, and

ig. 6 is aside-view of the same and in its final form.

Referring now to the drawings, it will be seen that the door comprises and is made up of a plurality of channel sections 1 which are adjaeently placed as clearly shown in 1 The length of the sections, of course, depends on the desired height of the door, and any multiple of sections may be used depending on the width desired for the door.

Channel sections are made up in standards of different widths and it will be understood that if multiples of saythe size shown do not make in the aggregate the desired width,

sections of a greater or lesser width would be used.

The flanges 2 of each channel section are further bent to form the relatively small inwardly extending flanges 3.

After the proper number of sections of the desired width are placed in position an angle iron 4 is placed along their upper ends so that its Webs 5 will abut against all of the ends of the sections, and the flange 6 of the angle iron will extend acrossthe face or web of each of the sections 1.

Each section is then riveted to the flange 6 of the angle iron 4:, thus tightly holding each and all of the sections in their set and desired position.

A second angle iron 7 is likewise riveted to each and every section at their lower ends to thus completely reinforce the u peer and lower ends of the door, and all sections then I spot welded.

To further strengthen the door and to provide against the diagonal strains, a plurality riveted to the web 5 of the angle iron and the flange 10 being likewise riveted to the flange-2 of the channel section. It is also to be oarefulty noticed that one edge of the shown the manner in which they are applied, the flange 9 being securely neath the opposite small flange 3 of the same section.

By placing these gussets as above mentioned the door is greatly strengthened, each corner being box-like in cross-section, thereby providing as strong a structure as is possible to obtain with the amount of metal used. I

Of course these gussets may be made larger than shown in the drawing if desired and additional ones may be used along the upper and lower ends of the door if ever found necessary.

In Fig. 1 I have shown a plurality of holes 12, through which hangers (not shown) may be bolted, whil'e near one edge of the door I have shown openings 13 through which a has may be secured.

v hen used on freight cars it willbe desirable to place the door sothat the smooth surface is presented to the inner surface of the car, but on the other hand when used in other places either side may beused for the inner or outer side.

From the foregoing it willbe seen that I have provided a door construction which will be' relatively light in weight, may be of any width or he ght; it being necessary simply to use channels, the multiples of which give the desired width, and the manner of assembling is such that no great length of time will be -necessary inriveting the sections to the upper and lower angles which act as girders to which the strains and stresses are directed by the channels. Furthermore, by providing gussets as shown they havlng their body portion away from the inner side of the channel and fitting snugly beneath the small flanges a very rigid and strong construction is obtained.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A door construction comprising a plurality of channel sections, each of said sece channel section andtions having its flanges bent inwardly to form further flanges,-an angle iron extending'transversely of the upper ends of each section and one ofits'faces riveted to the faces of said sections and its other faceforming the upper edge of the door, a second angle memberv likewise secured at the lower ends of the sections to form the bottom of said door, reinforcing members at the four corners of said door, the body ortion of said reinforcing member in each tightly fitting beneath the aforementioned inwardly extending flanges and each reinforcing member being bolted to a flange of the channel section and to a face of the transversely extending angle member.

2. A door construction comprising a multiple of channel sections, each section having inwardly disposed flanges, an angle iron extending transversely of all of said sections and riveted to the face of each of said sections and the other face of said angle member forming the top surface of the door, a similar angle iron secured to the lower ends of each of said sections and likewise forming the bottom of the door, gusset members disposed in each corner of said door and snugly fitting beneath the adjacent inwardly extending flanges of the channel sections and the body portion of said gusset so disposed to form each corner of the door box-like in cross-section.

3. A door comprising a plurality of channel sections disposed lengthwise of each other, an angle iron having one face thereof riveted to each of said sections and the other face of said angle iron forming the upper edge of said door, a second angle iron having one face riveted to the faces of said channel sections at their lower ends and the other face of said angle iron forming the bottom of said door, reinforcing means secured at each corner of said door, the outer flanges of the two opposite outer sections forming the outer sides of the door.

In testimony whereof I affix my signature.

WILLIAM E. WINE.
